As a U.K. court rules that belief in global warming is akin to a religious or philosophical conviction, Jaymi worries about the implications of thinking of environmentalism as a belief (but not in a preachy way). In other news, Lloyd reports that climate change denial is on the decline, at least among business leaders.

The 10:10 campaign, a big U.K. effort to get ministries and companies to cut their CO2 emissions 10 percent by 2010, recently got an…

As we enter the home stretch leading up to Copenhagen, with talks moving to Barcelona, initial reports aren’t exactly encouraging. Will the United States step up and commit to a meaningful 2020 emission reductions target? And will China manage to reconcile its obligation to developing nations while working with the United States?

On the conundrum of recyclable packaging that doesn’t often get recycled, Pablo Paster takes another look at TetraPak, the company that makes aseptic milk…

Windmill wunderkind William Kamkwamba is a big star on TreeHugger, at GOOD, and, it seems, everywhere else these days. When we spoke with him at the very end of his whirlwind book tour, he told us about his hopes for his home Malawi, the highlights of his US trip, and the stress that comes not with devising a new DIY well drill but with the American college search.

Sometimes, in the battle between cars and people, it…

This week, TreeHugger spoke to Margaret Atwood, wondered what smart grids will mean for our privacy, learned some new ways of dealing with wayward poop, and watched nervously as bikers, pedestrians, and even clothesline-hangers fought for their rights.

A town of 200 people in the jungle of Colombia has no guns, no police, no cars, no mayor, no church, no priest, no cellphones, no television, no internet. But the solar energy, biofuel use, and enormous reforestation…

Just before he won the Nobel, Obama got dissed at climate talks in Bangkok. TreeHugger spoke with Oxfam’s lead climate representative about the contentious summit and what needs to happen next. World, know that America can be serious about this: the prospect of a climate bill passing before Copenhagen has just been rekindled, and California just levied a fee of 15 cents on each ton of big polluters’ greenhouse gas emissions to help pay for its landmark cap-and-trade system, set…

This week over at TreeHugger, we heard Arnold pushing forests at the sequel to the Governors’ Global Climate Summit (not as good as the Terminator sequel, he joked), watched a documentary on the David vs. Goliath battle of big beer and the microbreweries (this one’s for you, local beers), and mused on the viability of food waste-to-energy projects (let’s eat what’s on our plate first). We pointed out one of the best but little-known measures of a bikeable city (look…

Treehuggers were all over the map this week: Brian Merchant sat down with Bill Clinton on the sidelines of the Clinton Global Initiative, while Matthew McDermott had breakfast with IPCC Chairman Rajendra Pachauri. On the other end of the spectrum, we contemplated picking up dog poop and the virtues of peeing on our plants (see below).

In the photo department, a few Treehuggers checked in on PARK(ing) Day around the country, Jacob Gordon checked out the sustainable offerings…

Google builds its own servers because the commercial ones are too expensive. It’s also building solar panels for the same reason—and by focusing on mirrors, the company thinks it can cut the cost of solar energy by 60 percent. Overachievers. (They’re going to do it, aren’t they?)

While we’re talking about dramatic percentages, an engine developed in England takes up 50 percent of the volume of a regular engine but gives twice the torque for the same…
